you've seen me use this set time and time again. the only difference is i went with Careful Nature to help it be more Specially Defensive and ran Shed Shell so Magnet Pullers like Magnezone don't OHKO it before it sets up.

This ones tricky. Air Balloon and Flash Fire let it switch into Fire and Ground type attacks, which are 2/3 of the types that are most likely going to target Steel teams. Fire Blast is STAB even though its Accuracy sucks sometimes, it has the perk of being boosted by Flash Fire and STAB if i can switch it into a Fire attack. Earth Power is coverage and also has the perk of lowering the opponents SDef if hax is on your side. Flash Cannon is STAB and is also neutral coverage overall. also acts like Earth Power on the SDef.

Lif Orb attacker. Hone Claws boosts Atk and makes Meteor Mash more reliable. Earthquake is friggin' Earthquake. Bullet Punch is +1 Priority and STAB which can easily pick weakened teams apart late game. Usually avoids the fight till the opponents 4th Pokemon or so, then it can set up and demolish all that still stands before the might mech .
